Specification of Letters Patent.

Patented Dec. 11, 1917.

Continuation of application filed March 9, 1912, Serial No. 682,739. This application filed October 11, 1913. Serial No. 794,566.

To all whom it may concern:

Be it known that I, Vwron VON Somm- GELL, a citizen of the United States, residing in the city, county, and State of New York, have invented certain new and useful Improvements in Window-Frames, of which the. following is a specification.

This invention relates to window-frames and is directed primarily to the provision of a window-frame for use in a railway paspaneling of the wall of the car adjacent to the frame and the provision of efficient insulation against the passage of heat through the wall of the car.

In constructing pressed steel passenger railway cars heretofore, it has been the prevailing practice to make up the multiplicity of parts for a car wall including the numerous parts for the several window-fraines which are to be incorporated in the wall and after all of these parts have been properly constructed and taken to the place where the work of assemblage is performed, the wall is built up by adding the parts one after another. I have found that the work of erecting such a car is greatly facilitated and its cost materially reduced by making windowframes for railway cars in the form of c0mplete window-units which may be shipped in their complete form from a place of manufacture having special facilities for the manufacture of window-frames to a car builder, these units to be there inserted in openings in the wall of a car which wall has been completed except for the insertion of the window-units. This procedure offers important advantages additional to the reduction in the cost of manufacture of the cars, particularly in that it facilitates mak ing the window-frames so accurately that the sashes will operate therein easily and at the same time will "fit so snugly as to preclude passage of air about the edges thereof to an undesirable extent. Furthermore the 4 metal window-sill, side-members formed of sheet-metal strips extending upwardly from the ends of this sill and one or more metallic cross-members connecting the upper ends of the side-members. Each of the sidemembers of the frame is made of two sheetmetal strips which are united at their adjacent edges but. have insulating material inserted between those edges so that heat will not readily pass through the metal of the side-members of the frame from the interior to the exterior and vice versa. One or more sashes are arranged within the frame and adapted for vertical movement in suitable guides. Above these sashes are a sheetmetal panel and a metallic curtain-box, both of which extend between the side-members of the frame and are secured thereto. These two parts, the panel and curtain-box, are

secured to the inner strips of the side-members and do not contact at all with the outer strips of those members. In the manufacture of railway ears, there are always slight differences in the size and shape of the several window-openings and in order that the completed car wall may have a more attractive appearance, the window-frames are so constructed as to provide for a vertical adjustment of the panel or both the panel and curtain-box upon the side-members of the window-frame so that. the panel may be secured in such a position that its upper edge will coact properly with the parts of the car wall immediately above the windows, such for instance, as the usual cornice running lengthwise of the ear wall. The present application is a continuation of my Patent No. 1,091,770, dated March 31, 1914, for ear construction, certain features being disclosed therein, and others being improvements over the disclosure thereof.

The preferred embodiment of the invert tion is illustratedin the accompanying drawiugs. in which Figure 1 is a front view of the frame, the guides for the curtain and sashes being removed, Fig.2 is a vertical section of the unit on an enlarged scale, broken away in part, Fig. 3 is a top view of the window-unit, Figs. 5 and 6 are horizontal sections on lines H. 55 and 66 of Fig. 2 and Fig. 7 is a sectional detail view illustrating a slight modification of the construction shown in certain of the other figures.

Referring to these drawings, the windowframe is of rectangular form and consists of sheet-metal frame members secured together at their ends. The sill is shown at 8 and consists of a sheet-metal strip pressed into suitable form such as that illustrated in Fig. 2. The side-members of the frame are secured at their lower ends tothe ends of the sill S and extend upwardly therefrom in parallelrelation. Each of these side-members consists of an inner and an outer sheet-metal strip and these two strips are secured together with insulation between them preferably byhaving the edge of one strip overlap the edge of the other strip and the insulation between the overlapping edges. The inner strip is shown at 9, the outer at 10 and theii'isulation at 11. As shown in the sectional views Figs. 4, 5 and 6, the two strips 9 and 10 of a sidemember have their ad acent edges overlapping and the strip of insulating material which extends the entire length of the strips 9 and 10 is located between these overlapping edges. The two strips and the insulating material are secured together in any suitable manner, as for instance, by'

rivets l2.

Therectangular frame is completed by cross-members which connect the upper portions of the side-members. Preferably two such cross-members are employed, these being separated one from the other and one of them connecting the inner strips 9 while the other connects the outer strips 10. The inner strips 9 are connected by a cross-member 13 in the form of a rail of angular crosssection. This is secured at its ends to the strips 9 in any suitable manner as by welding thereto. The outer strips 10 are connected to a cross-member 14 of channel section welded at its ends to the strip 10.

The two strips of each-of the side-members are provided with flanges at their non-adjacent edges. The flange 15 on each outer strip 10 is turned inwardly of the frame. These flanges 15 are provided for coaction with the exterior sheathing of the wall of the car. The window-unit constructed in accordance with this invention is adapted to be inserted in a window-opening in the wall of a car by inserting the window-unit in the opening from the interior of the car. The exterior sheathing of the car is made to overlap the edges of the window-opening slightly and the window-unit is moved into the opening until the flanges 15 abut against the overlapping edges of the sheathing. The window-unit is then secured in position in the opening in any suitable manner, as for instance, by detachable bolts passing through openii gs in the flanges 15 and openings in the coacting edges of the sheathing.

The inner edge of the inner strip 9 of each side-member of the frame is provided with a flange 16 extending outwardly of the frame. This flange 16 is adapted to coact with a sheet-metal panel forming part of the car wall and extending between two adjacent window-frames. The wimlow-frame is therefore provided with attaching means for coaction with the panel. In the present instance, this attaching means is shown as a sheet-metal strip 17 secured in any suitable manner to the inner side of the flange 16 ot' the strip 9. Its outer edge preferably extends beyond the edge of the flange 16 and is provided with a vertically disposed bead 18. When the wimlow-umt is completed, the attaching means 17 takes the position illustrated in Fig. After two adjacent window-units have been installed in their openings, the edge of a sheet-metal panel is inserted between the strip 17 and the flange 16 of one window-unit and the opposite edge is then inserted under the flange of the next adjacent unit, the panel being moved for this purpose in one direction and then a short distance in the other. The insertion of a panel in this manner moves each of the attaching strips 17 to the relation in which they are shown in Figs. 4, 5 and 6. This form of attaching means, especially when rovided with the head 18 therein, holds t 1e panel rigidly and prevents rattling of the parts when the car is in use, the bead pressing against the panel.

A curtain-box formed of sheet-metal is shown at 19, this extending from one sidemember of the frame to the other. Above this curtain-box is a sheet-metal panel 20 which closes the frame above the curtainbox 19. A guide 521 is secured to each of the strips 9 of the side-members to guide the curtain in its movement and also to assist in positioning the inner vertically movable sash 22. A guide 23 is secured to each strip 10 of the side-members, this guide lying between the inner and outer sashes and 24. The panel 20 has the material at the lower edge thereof bent toward the outer side of the window-frame as shown at 25 in Fig. 2.

This lower portion of the panel'is arranged to enact with the inner sash 22 so as to preclude the entrance of air into the car over the upper edge of the sash 22. For this purpose, a weather strip 26 is secured to the upper portion of the sash 22 in position to coact with the lower edge of the panel 20 when the sash is in the closed position.

In the construction of railway cars, there is always a slight variation in the dimensions and shape of the openings for windows such that difficulty is experienced in making the several parts fit accurately. If no provision for adjustment were made, it would frequently occur that the several windowunits installed in the side wall of a railway car would not coactaccurately at their upper edges with the member or members immediately above the window-openings. In order to give the interior of a railway car a more attractive appearance by reason of the absence of a crack-or uneven formation at the top of the window-unit, I provide for an adjustment of the vertical position of the panel upon the side-members .of the window-frame. In the present instance, the panel 20 is shown as having the material at the upper edge thereof turned o er and down at 27 so that this may be moved down more or less upon the vertical web of the rail 13. Near its lower edge, this panel is secured in any suitable manner to a rail 28 of angular cross-section and of such length that it extends from one side-member of the frame to the other. Below the rail 28, the

material of the panel 20 is formed for 00-- action with brackets 29, one secured to each of the strips 9 of the side-members of the frame. These brackets 29 have vertically disposed slots in the outwardly extending webs thereof adapted to receive bolts 30 Which bolts also pass through openings in the extension 25 of the panel 20. When assembling a window-unit initially, the panel 20 is mounted upon the frame with its upper extension 27over the rail 13 and its lower extension 25 lying against the brackets 29, and the bolts 30 are inserted through the slots in the brackets 29 and the openings in the extension 25 so as to hold the panel in position. After the window-unit has been inserted in its position in the car wall, the

bolts 30 are loosened and the panel 20 is then moved vertically such amount as is necessary to cause its upper edge to contact with the part of the car wall immediately 1 above the window-unit, usually a cornice running lengthwise of the car. When the panel has been properly positioned thus, the bolts 30 are tightened up to hold. the panel rigidly and additionally one or more cold rivets 31 are preferably inserted through the bracket 29 and the extension 25 of the panel to assistin securing the panel in position.

The rail 28 has supports 32 secured to and depending from its ends, these supports being provided with openings or other suitable means for receiving and sustaining the ends of a'curtain roller. This roller is in- 1 closed within the curtain box 19 which is secured in position by screws 33 engaging I the rail 28 and screws 34 engaging horizontel ears formed on the plates 32. The curtain-box 19 is therefore detachable to permit of inserting and removing the curtain and when in position it is mounted upon the panel 20 so that it and the'panel are adjusted vertically together. The range of adjustment of these parts necessary for the purpose above mentioned is very small as it is only necessary to provide for enough adjustment to compensate for irregularities in the arrangement of the other parts of the wall. The ends of the curtain-box are closed as is indicated in Fig. 1 and extend over.

upon the flanges 16 of the inner strips 9 of the side-members so as to present an attractive appearance at these Ipoints.

The panel 20 prefera ly has its lateral edges turned inwardly as shown at 35 in Fig. 4 so that these lateral edges lie close against the inner strips 9 of the side-members of the frame. Preferably retainin strips 36 are provided for coaction wit these side flanges 35 of the panel 20. These strips 36 are secured to the strips 9 and are bent intermediate their edges asshown in Fig. 4 so as to inclose the flanges 35 of the 111%13116 panel firmly.

eferring now to Fig. 7, a modified construction is shown whereby proper coaction of the upper edge of thewindow-unitwith the overlying cornice is secured. The cornice is shown. at 38 and its upper edge is secured to the wall structure while its lower edge is unsecured until the window-unit is tlghtened up in position. This cornice is formed of sheet-metal and its unsecured lower edge is capable of slight vertical movement by reason'of the elasticity of the metal. In insertin the window-unit, the lower edge thereof is positioned upon the sub-sill of the car wall and then the upper portion of the unit is moved into the window-opening. As this is done, the upper edge of the panel 20 engages the portion 39 of the cornice and the latter moves upwardly sufficient to permit the edge of panel 20 to pass beyond it whereupon the cornice springs back to its original shape. for the window-unit including the bolts 40 are tightened up, the lower edge of the cornice 38 is gripped between the upper edge of the panel 20 and the wall structure and all of the parts are held firmly.

It will be appreciated that a window-unit When the securing means The constructed as herein described with the members of the frame secured rigidly to each other as by welding them together, will retain its shape so that the. sashes will move freely while fitting snugly therein and that when the unit is positioned with its sidemembers spaced from and not secured to the posts of the side wall, the sagging which takes place in the wall of the car including relative movement of the posts will not cause distortion of the frame and thus bind the sashes. Furthermore, such a complete window-unit may be readily inserted in a window-opening when assembling a car wall and thereafter may be readily withdrawn to permit of painting the interior surfaces of.

the metal parts of the window-unit and wall. Also, the construction herein described involving the provision of insulation in the side-membersof the frame greatly reduces the passage of heat through the windowunit from the interior to the exterior of the car and vice versa.

Having described my invention, what I claim as new therein and desire to secure by Letters Patent of the United States is:

1. A window-frame comprising a metallic window-sill, two metallic side-members secured at their lower ends to the sill, and a cross-member connecting the side-members near their upper ends, each of said sidemembers consisting of inner and outer sheet-metal strips having their adjacent edges secured together with insulating material between them, the inner strip having its opposite edge flanged outwardly of the frame, and sheet-metal strips secured to the outer sides of said flanges near one edge thereof and having beads therein near the opposite edges thereof, said beads being adapted to press against panels inserted between said beaded strips and said outwardly extending inner strip flanges, substantially as set forth.

2. A window frame comprising a sill, two metallic side members secured at their lower ends to the sill, a metallic cross-member connecting the upper ends of the side members, a. sheet-metal panel extending between the side members, and having its up er edge turned to extend about the upper e ge of said cross-member, in such manner as to permit some vertical movement of said panel without disengaging the upper edge of said anel from said cross-member, and means f dr securing the panel to the side members in various adjusted positions, substantially as set forth.
